The World Health Organization (WHO) has released new guidelines on the treatment of chronic pain in children, recommending that prescription opioids only be used for children who are dying or seriously ill and not expected to recover.

The 56-page guideline calls access to pain management a “fundamental human right,” while at the same time warning that “evidence of the effectiveness and safety of opioids is completely lacking in children.”

The guideline emphasizes the use of physical and psychological pain therapies, while taking a cautious approach to opioids. Morphine is only recommended for children in palliative care and those with “life-limiting” conditions for which there is no cure and “an early death is expected.”

“Children who are appropriately prescribed morphine for chronic pain in the context of end-of-life care or in children with life-limiting conditions, may require morphine for the management of intercurrent, acute or breakthrough severe pain,” the guideline states.

“Time-limited use of morphine in these contexts should be at the lowest appropriate dose and duration possible and must be regularly reviewed in order to ensure the fewest possible adverse events. Healthcare providers and caregivers need to perform frequent and repeated reassessments of pain and other symptoms, and the principles and relevant guidelines for acute pain management should be followed, including having an opioid stopping plan.”

The new recommendations for children between 0 and 19 years of age are a marked departure from previous WHO guidelines for chronic pain, which said that opioids “are known to be safe and there is no need to fear accidental death or dependence.”

Those guidelines were withdrawn in 2019, after two U.S. congressmen accused the United Nation’s health agency of being “corruptly influenced” by opioid manufactures.  A coalition of palliative care organizations objected, saying WHO caved-in to political pressure.

“We are extremely concerned that the withdrawal of these guidance documents will lead to confusion and possible extreme measures that will hinder access to patients with legitimate medical needs,” the coalition said in a joint statement. “Lack of availability and limited access to these medications for legitimate medical treatment is a human rights violation.”

‘Very Low Certainty’ of Evidence

Most of the recommendations made by a WHO advisory panel – the Guideline Development Group (GDG) — are vague, conditional and based on “very low certainty” of evidence. One of GDG’s members was Andrew Kolodny, MD, a psychiatrist and addiction specialist who founded Physicians for Responsible Opioid Prescribing (PROP), an anti-opioid activist group.

Despite an admitted “paucity of high-quality research” on how to treat pain in children, the GDG recommended that children be treated from a “biopsychosocial perspective” that incorporates physical therapy and psychological interventions such as cognitive behavioral therapy.  

“Children with chronic pain and their families and caregivers must be cared for from a biopsychosocial perspective; pain should not be treated simply as a biomedical problem,” the GDG said.

There is surprisingly little discussion in the guideline about the risks and benefits of non-opioid drugs such as acetaminophen. Some of the recommendations border on platitudes, such as treatment being “child and family-centered” and “tailored to the family’s values, cultures, preferences and resources.”

One area where the GDG is adamant is the importance of treating childhood pain to prevent it from becoming a lifetime problem.

“Exposure to chronic pain in early life may have implications for the incidence, severity and duration of chronic pain, and may be associated with long-term, maladaptive neurological changes,” the guideline warns.

“Chronic pain in childhood is associated with progression of pain into adulthood and potentially predisposes these children to other chronic health problems in later life. The negative impacts of chronic pain also extend to family members who report a higher burden of care and a detrimental effect on family function. As such, chronic pain during childhood has a very significant negative impact on the child over their life course as well as their wider family unit, making appropriate diagnosis and management essential.”  

The GDG said large, multi-center trials are needed to examine the safety and efficacy of virtually all pain management therapies. Additional research is also needed for children suffering from cancer pain and those with developmental and intellectual disabilities.

Former President Trump withdrew the United States from WHO last year in a dispute over its handling of the COVID-19 pandemic. President Biden reversed that decision on his first day in office.
